A one-piece cutting head for a drill bit includes a main cutting edge that extends between radial extremities of the cutting head. The main cutting edge is disposed between main rake surfaces and main relief surfaces. Each main rake surface includes one or more rake facets, and each main relief surface includes one or more relief facets. Adjacent rake facets and relief facets define a primary transverse edge therebetween that extends away from the main cutting edge. The cutting head further includes a plurality of side cutters that are transverse to the main cutting edge and that propagate from the primary transverse edge to a radial extremity of the cutting head. Each side cutter includes a side cutting edge between a side cutting rake facet and a side cutting relief facet.

A masonry drill head is made from a sintered cemented carbide. The masonry drill head has an at least section-wise planar joining end for heat induced joining to a shaft, a working end for shattering masonry material under a percussive motion, at least two conveying webs each emerging from the joining end and at least two conveying grooves each extending between two of the conveying webs. A cross-sectional solid material area of the masonry drill head increases towards the joining end, such that a masonry material debris intake of at least one of the conveying grooves increases towards the working end.
